Dear Mr. Collins:
In response to our telephone discussions on January 7, 2005, this letter documents PSEG Nuclear LLCs (PSEG) commitments regarding the Hope Creek B Reactor Recirculation Pump.
- 1) PSEG will implement a vibration-monitoring program to continuously monitor the B Reactor Recirculation Pumps primary and secondary harmonic parameters (total amplitude, 1X and 2X amplitude, and 1X and 2X phase angle) during future operating cycles. This program shall include establishing objective criteria that demonstrate that monitored parameters are within acceptable range and developing procedures which specify the actions to be taken if the monitored parameters are outside of the specified range of the acceptance criteria. We understand that PSEG p roced u res H C. 0 P-AB. R PV-00 03 (Q), H C. 0 P-AR. ZZ-0 0 0 8 (Q)
Attachment E-4, and HC.ER-AP.BB-OOOl(Z) Rev. 0, provided by PSEG letter dated January 4, 2005 meet this commitment.
Further, this program will continue until an inspection of the B Reactor Recirculation Pumps rotating assembly and replacement of the pump shaft have been completed.
Mr. Samuel Collins LR-N05-00 17 2
- 2) PSEG will notify the NRC prior to implementing any change to the vibration monitoring and operating procedures cited above. This notification will provide sufficient time for the NRC to complete a review of the proposed changes.
- 3) PSEG will replace the B Reactor Recirculation Pump shaft and inspect the pumps rotating assembly and pressure boundary components (such as the pump casing and cover) at the earlier of the next refueling outage (RFOI 3) or during an outage of sufficient duration to accomplish pump replacement.
During the current refueling outage (RF012) PSEG has completed extensive work directed toward improving equipment reliability and correcting long-standing problems. Attachment I provides a summary listing of some of the more significant activities.
Should you have any further questions please contact Christina Perino, Director-Licensing and Nuclear Safety at 856-339-1 989.
Very truly yours, n
